Filter unit {filter unit}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter unit, and more particularly, to a filter unit using a plurality of sheets of paper material.

In general, filter elements for engine oil filtration of industrial oils and automobiles are made of paper filter paper.

The filter paper of the paper ash is made of pure pulp without sizing or escaping by using pulp of softwood with a long fiber and little resin such as fir, cypress, spruce,

An oil filter using such a paper material filter paper is variously disclosed in Korean Patent No. 10-0569933.

On the other hand, in the case of a paper material made of a pulp material, the water-soluble liquid can not maintain its filtering function because pulp is loosened and adhered to each other, so that only water-insoluble liquids such as oil are used for filtration. have.

It is an object of the present invention to provide a filter unit capable of filtering a water-soluble liquid while applying filter paper made of pulp paper.

According to an aspect of the present invention, there is provided a filter unit comprising: a body having a hollow and having a through hole communicating with the hollow on an outer surface thereof; First and second support pieces provided to be spaced apart from and opposite to each other on an outer surface of the main body; A first sheet made of a paper material and a second sheet made of a waterproof material are alternately stacked between the first and second support pieces to provide a filtration path to the through hole and the hollow through the first sheet, And a sheet stacked body capable of filtering the object.

4 is an exploded perspective view illustrating a filter unit according to a third embodiment of the present invention.

Hereinafter, a filter unit according to a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a sectional view showing a filter unit according to the present invention, and FIG. 2 is an exploded perspective view showing a part of a filter unit of FIG. 1.

1 and 2, a filter unit 100 according to the present invention includes a main body 110, first and second support pieces 121 and 122, and a sheet stack 130. [

The main body 110 has hollow hollows 112 along its longitudinal direction and a plurality of through holes 116 communicating with the hollows 112 are formed on the outer side surface 114.

The main body 110 is formed in such a structure that one end 110a is closed and the other end 110b is open.

One end 110a of the main body is formed with a coupling groove 117 which is inserted inwardly so as to be able to fasten the bolt 140 so that the first supporting piece 121 described later can be mounted and a screw thread is formed on the inner peripheral surface.

The other end 110a of the main body is formed with a thread engagement portion 118 having a thread on the outer side surface 114 so that the second support piece 121 described later can be mounted by screwing.

The first support piece 121 and the second support piece 122 are spaced apart from and supported by the outer side surface 114 of the main body 110 so that the first and second support pieces 121 and 122 can restrain the sheet stack body 130, Is installed.

The first supporting piece 121 has a through-hole 121a at the center so that the body of the bolt 140 can be inserted.

The inner diameter of the through hole 121a of the first support piece 121 is smaller than the outer diameter of the main body 110. [

The first support piece 121 has a thickness not to cause a warp and is formed of a metal material or a synthetic resin material.

The second support piece 122 may also be screwed to the threaded engagement portion 118 having a through hole 122a at the center thereof and a threaded portion formed on the outer side surface 114a of the other end 110a of the body 110 And is formed to have a screw thread on the inner peripheral surface.

The second support piece 122 also has a thickness not to cause warping and is formed of a metal material or a synthetic resin material.

Needless to say, the second support piece 122 may be integrally formed or welded to the main body 110, unlike the illustrated example.

The sheet stack 130 includes a first sheet 131 made of a paper material and a second sheet 131 made of a waterproof material on the outer surface 114 of the body between the first and second support pieces 121 and 122 132 are laminated so as to be in close contact with each other.

The first sheet 131 is made of a paper material that can be filtered by surface roughness and has a first insertion hole 131a at the center so as to be inserted through the outer surface 114 of the main body 110 Respectively.

The first sheet 131 provides a filtration path by surface roughness of both side surfaces contacting with the second sheet 132.

Here, the thickness of the first sheet 131 is 0.05 mm to 2.0 mm. The surface roughness of the first sheet 131 has a maximum height Rmax of 0.5 to 25 占 퐉.

If the thickness of the first sheet 131 is thinner than 0.05 mm, it is difficult to maintain the desired surface roughness and it is difficult to exhibit filtration ability. If it is thicker than 2.0 mm, the thickness of the non- The capacity is excessively reduced on the basis of the length of the main body 11, so that it is difficult to exhibit filtration performance.

In addition, the second sheet 132 is formed of a waterproof material so as to prevent transmission of liquid.

A second insertion hole 132a is formed at the center of the second sheet 132 so as to be inserted into the outer surface 114 of the main body 110. [

The second sheet 132 is made of a metal material or a synthetic resin material that is a waterproof material and almost incompressible.

The second sheet is formed of, for example, a metal material such as aluminum or stainless steel, or a synthetic resin material such as polypropylene, polyethylene, PET, or PVC.

Here, the thickness of the second sheet 132 is 0.05 mm to 2.0 mm, and the surface roughness Rmax is 0.1 to 10 占 퐉.

If the thickness of the second sheet 132 is less than 0.05 mm, defects may occur due to tearing or the like in the assembling process. If the second sheet 132 is thicker than 2.0 mm, the filtration area ratio on the main body 110 is excessively reduced, it's difficult.

In addition, if the surface roughness of the second sheet 132 is lowered by a maximum height Rmax of 0.1 占 퐉, the processing cost burden is large. If the surface roughness is larger than 10 占 퐉, the filterable size becomes large.

The sheet stack 130 is formed by alternately stacking a first sheet 131 having a filtering function and a second sheet 132 having a non-filtering function and a waterproof function, Thereby providing a filtration path to the through hole 116 and the hollow 112 through the first sheet 131. [

Particularly, since the first sheets 131 are separated from each other by the second sheet 132, the loosening and binding of the pulp between the first sheets 131 is suppressed, Can be formed independently to provide filtration performance for an aqueous liquid.

On the other hand, an elastic bias is applied in a direction in which the first support piece 121 is brought closer to the second support piece 122, so as to maintain the close contact pressure between the first and second sheets 131 and 132 And an example thereof will be described with reference to Fig. Elements that perform the same functions as in the preceding figures are denoted by the same reference numeral.

Referring to FIG. 3, the elastic bias portion 250 is coupled to the main body to elastically bias the first support piece 221 in a direction toward the second support piece 122.

The elastic bias portion 250 includes a third support piece 251, a bolt 140, and a spring 225.

First, the first support piece 221 is inserted through the outer surface of the main body 110 and has a through hole at the center so as to be moved along the outer surface of the main body.

A sealing o-ring 223 is inserted into the bottom surface of the first support piece 221.

The third support piece 251 is formed in a disc shape having a through hole 151a at the center so that the body of the bolt 140 can be inserted.
